MBE Rules · Criminal Law
MPC mens rea — purpose / knowledge / recklessness / negligence
MPC §2.02
The rule
MPC: (1) Purposely — conscious objective; (2) Knowingly — aware that conduct is of that nature or result is practically certain; (3) Recklessly — conscious disregard of substantial and unjustifiable risk; (4) Negligently — should be aware. Bar default: recklessness if statute is silent.
In plain English
To be guilty, a person must have a certain mindset: on purpose, knowing the likely outcome, ignoring big risks, or not noticing obvious risks. If the law doesn't say, assume it's about ignoring risks.
Worked example
The defendant sets off fireworks in a dry field, aware it might cause a fire (recklessness). The field burns, and the defendant is liable because they ignored a big risk.
Memory hook
Purposely, Knowingly, Recklessly, Negligently: PKRN — Purpose is king, Reckless is default.
The trap
Students think: if silent, any mens rea applies. Wrong, because MPC defaults to recklessness. The actual test is to assume recklessness unless otherwise specified.
How examiners test it
The MBE loves: ambiguous statute with no mens rea. Question: which applies? Trap: overlooking that recklessness is the default assumption under MPC.
